摘要： A mitigation control system, for performing an active hazard mitigation method, is arranged in an environment containing an energetic material and includes an abnormal temperature sensor for detecting an abnormal temperature of the environment, a power source that is mechanically actuated by the abnormal temperature sensor when the abnormal temperature exceeds a predetermined abnormal temperature threshold, a mitigation controller that is actuated by the power source, and a plurality of local temperature sensors that are communicatively coupled to the mitigation controller and are arranged for detecting critical temperatures in specific regions of the environment. The mitigation controller executes a mitigation action when one of the critical temperatures exceeds a predetermined critical temperature threshold for the corresponding specific region.

摘要： Embodiments are directed to direct impingement cook-off mitigation systems. As assembled, a munition fuzewell is torqued into the aft end of a munition. During a cook-off event, the expanding gases from the booster energetic will burn instead of detonating. The hot expanding booster gases are vented to the munition's main fill energetic causing the main fill energetic to burn concurrently with the booster energetic. The combined expanding gases from both the booster and main fill energetics are then vented through longitudinal vents.

摘要： The disclosed embodiments are directed to enhancing insensitive munitions performance. Some of the embodiments employ an outgassing pad having unique geometrical configurations, compositions, and positioning. Other embodiments rely on using thermally-releasable components to foster billet expulsion. Additional embodiments combine both aspects into entire cook-off mitigation systems for insensitive munitions improvements.

摘要： An ammunition cartridge comprised of a projectile inserted in, and mechanically connected to, a metal cartridge case assembly having a propulsion chamber and a base, and an energetic propellant disposed in the propulsion chamber, includes a base plug in which is mounted an igniter with an energetic primer. During manufacture of the cartridge, a fusible support ring is incorporated into a metal cavity. The cartridge base includes a cavity allowing the fusible material to solidify at ambient temperatures. When exposed to heat from an external fire, the fusible support plug liquefies losing its strength and subsequently, when a propellant or primer off-gasses or auto-ignites the pressure from the reaction ejects a metal plug or lid from the cartridge case base, creating a void that allows the propellant and primer to combust in an unconfined space.
